Low Jitter Oscillator Generates any Frequency from 10 MHz to 1.4 GHz®Hardware designers have traditionally used multiple
fixed-frequency XOs, VCXOs or voltage-controlled SAW oscillators
(VCSO) in designs requiring a system timing architecture that is
reconfigurable to operate at different frequencies. This approach is
expensive, requires complex analog phase locked loop (PLL) design and
layout and slows time-to-market for new hardware designs.
The Si570/1 programmable XOs and VCXOs replace multiple
fixed-frequency oscillators with a single, frequency-flexible
oscillator that can generate any frequency from 10 MHz to 1.4 GHz,
significantly reducing component count, system cost and board space
while simplifying PLL design and layout. The Si570/1 offer improved
system reliability because multiple fixed-frequency oscillators, each
representing a potential point of failure, are eliminated.
The Si570/1 operating frequency is user-programmable via an
industry-standard I2C interface, simplifying device programming and
easing reconfigurability. The Si570/1 can be reprogrammed an unlimited
number of times, enabling system designers to reuse a common timing
architecture across a wide range of end applications, simplifying
design and speeding time-to-market.
"We've applied our proven DSPLL technology to dramatically
simplify timing architectures in applications requiring multiple clock
frequencies. The Si570 XO and Si571 VCXO address the growing need for
low jitter, frequency-flexible clock sources, enabling hardware
designers to decrease the number of oscillators in their designs while
reducing cost and design time," said David Bresemann, vice president
of Silicon Laboratories. "With the addition of the Si570/1 family of
any-rate oscillators, Silicon Labs has created the industry's broadest
portfolio of reconfigurable, frequency-agile precision clock and
frequency control products."
The Si570/1 devices are available in an industry standard,
RoHS-compliant 5 x 7 mm surface mount package with support for all
common output formats (LVPECL, LVDS, CMOS and CML). The family offers
three speed grades: 10 MHz to 1.4 GHz, 10 MHz to 810 MHz and 10 MHz to
215 MHz. The Si570 Any-Rate XO is available with two temperature
stability options, +/-20 ppm and +/-50 ppm. The Si571 Any-Rate VCXO
has a wide selection of absolute pull range (APR) options ranging from
+/-12 ppm to +/-375 ppm, giving hardware designers increased
flexibility when choosing the best device for an application. The
Si570/1 support operation from -40 to +85 C.
Pricing and Availability
Available now, the Si570 is priced from $10.02 to $54.79 in
quantities of 1K depending on speed grade and temperature stability.
The Si571 is priced from $23.39 to $122.76 in quantities of 1K
depending on speed grade and temperature stability.
